Just to be sure and have clarification of that at first, is the NFC of the Smartwatch 3 just an embedded tag or is it a theoretically fully functioning NFC-chip?
Hoping it's not just a tag, we want to build an Android Wear app using NFC and for this the biggest question is:
Thanks, Chris
TLDR: Basically it's the same question for the new smartwatch 3 of sony: Is NFC usable for developers? Is there an NFC API for the Sony SmartWatch 2?
There is a fully functional chip in the SmartWatch 3. It is today acting according to the spec linked by CM787 (here's a new one as the old one seems dead).
When Android Wear officially expands on the support for NFC, the SmartWatch 3 will be able to follow.
